'Your daughter is dead.' When Kat Cavanaugh hears the words every mother dreads, her perfect world shatters. She takes in the beautiful long blonde hair, torn yellow dress and chipped blue nail-varnish. It can't be real. And then the police add the word 'suicide'. But Kat refuses to believe them. Even when they show her the familiar looping handwriting and smudged ink on the note her little girl left behind. She knows her bubbly, vivacious daughter would never take her own life. As she searches Grace's perfume-scented room, filled with smiling photos, she uncovers secrets her daughter had been hiding. Secrets that make her wonder how well she really knew the woman her only child was becoming. Kat's determined to find out what really happened to Grace on the night she died, even if it means facing her own troubled past. But as she gets closer to the terrible truth, Kat finds herself faced with an unthinkable question: there was no way she could have protected Grace - or was there? The must-read psychological thriller for 2019 from the million-copy-bestselling author of Silent Child, perfect for fans of Behind Closed Doors and The Girl on the Train.
